New laser technology, known as free-form dual-comb spectroscopy, quickly measures gases of interest by homing in on the most information-rich parts of a sample.
Researchers at the National Institute of Standards and Technology (NIST) have upgraded their laser frequency-comb instrument to simultaneously measure three
After the optical frequency comb made its debut as a ruler for light, spinoffs followed, including the astrocomb to measure starlight and a radar-like comb
In a significant advance toward the future redefinition of the international unit of time, the second, a research team led by the National Institute of
Investigating colors in the wind — NIST researchers expand beyond a current spectroscopy technique for measuring greenhouse gases to now detect volatile organic
Researchers at the National Institute of Standards and Technology (NIST) have used a laser detection and ranging (LADAR) system to image three-dimensional (3D)
Accurately detecting, locating and quantifying leaks of methane, the main component of natural gas and a major fuel source worldwide, is critically important
Researchers from the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder have demonstrated a new mobile, ground-based
NIST researchers have devised a way to synchronize the time of two different clocks – separated by as much as 4 km of open, turbulent air – to within a few
A PML team is hitting the road with a fine-tooth comb. Scientists in the Quantum Electronics and Photonics Division have devised a portable optical frequency
